HEEL TRIMMER.

SPECIFICATION forming part of Letters Patent No. 399,153, dated March 5 1889.

Application filed March 13, 1886. Serial No. 195,163. (No model.)

trimming machine described in Letters Patv ent of the United States numbered 80,953, dated August 11, 1868.

The objects of my invention are, first, to provide the cutter with a loose collar that shall act as an anti-friction guard to protect 5 counter of the shoe determines the shape of the upper or counter of the shoe or boot while the heel is being trimmed, and also act as a '3 guide to determine the form of the upper portion of the heel, thereby making the counter portion of the shoe and the upper portion of the heel nearest to the upper conform to each other; secondly, to provide a tread-guide and top-liftguard that will admit of trimming a heel that is straighter on the side and near the breast than it is at the rear, thereby adapting the m achine for trimming heels that present different angles at eachsection from breast to rear without removing the corner of the top lift from the angle formed by the treadguide and the guide or stop for the edge of the top lift.

My improved machine is illustrated in the 1 accompanying drawing, which shows a tool embodying my invention.

It is obvious from the drawing that the side of the heel farthest from the cutter must be moved down in the direction of the dotted line a: .1, in order to trim the heel at all the varying angles form ed by the surfaces of the tread and side of the heel as they successively occur from breast to rear of the heel.

A represents a part of the frame of the ma chine. The table or treadguide is marked B, the arbor C, and the cutter D.

E is the guide for the edge of the top lift. The bushing F is slightly longer than the loose collar G, so that when the screw H is forced home the bushing F clamps the cutter D firmly in place and forms a journal to supthe top lift in the angle formed by B and E and the counter or upper of the shoe against the collar G, and then turns the boot or shoe so as to bring every part of the sides of the heel in contact with the cutter D, and thus the shape of the top lift determines the form of the heel at and near the tread, and The that part of the heel near the upper.

Vith my improved machine a large class of heels (and the very great majority of modern heels are of that class) can be trimmed which could not be trimmed upon the machine shown in Patent No. 80,950,Wl1ll8 my improved machine is also well adapted forthe old style of heels.

1 am aware of Foster and Tolless patent, No. 190,482, dated May 8, 1877, and Busells patent, No. 213,806, dated April 1, 1879, and disclaim all that is shown in them.

lVhat I claim as my invention is 1. The improved heel-trimming machine above described, consisting of table B, cutter D, top-lift guide E, and collar G, the surface of the table being inclined to the axis of the cutter-arbor C, the table being recessed to receive the top-lift guide E, and the collar G being held by means substantially such as are shown, substantially as described, and for the purpose set forth.

2. In a heel-trimming machine, the table 13, with its surface inclined to the axis of the cutter, in combination with the cutter D and the top-lift guide E, the table B being recessed to receive the top-lift guide, substantially as and for the purpose set forth.
